.DISCUSSION...Showers will impact the fire weather area
throughout today, with showers retreating to the mountains
tonight. There are widespread chances (15-30%) of isolated
thunderstorms through this evening. Winds will increase across the
lower elevations and through the Cascade gaps late this afternoon,
with peak winds expected to develop tomorrow afternoon. A brief
dry period will develop Sunday night with light winds, before the
next round of mountain showers and breezy winds develop Monday.
***Thunderstorms imply strong gusty winds***
***Winds are 20 foot 10 minute averages***
***CWR-chance of wetting rain 0.10 or greater***
***Ventilation Index is derived from the
transport wind multiplied by the mixing
height in 100`s of feet. Index categories
are a generalized indicator and users are
encourage to develop criteria that are
suitable and representative of dispersion
conditions in their local area of interest.***
Note: Max transport winds may not occur
at the same time as max mixing height.
